3 days: The technetium used for the study loses half of its energy each 6 hours. After 10 half lives all is safe. 60 hrs or about 3 days.

2 days is plenty: Switching you baby to formula for 2 days after the hida is plenty. Your body excretes the tracer faster than its actual half-life. After 2 days, you can resume exclusive breastfeeding safely.

48 hours: Technetium 99m is the isotope tagged to hida. It has 6hr half life. Usually by 24 hours most of it has decayed, but for most safety 48 hours would be 8 half lives.

3 days: 3 days should be safe. The radiotracer (radioactive material) used for the study should be out in the urine by then.

48 hours.: Hida is labeled to 99mtc-technetium, which is a radioisotope with a physical half-life of 6 hours, meaning that the radioactivity decreases by 50% every 6 hours. Usually 24 hours should be enough but generally we suggest to patients to do it for 36-48 hours if they can. At that time, most of the radioactive compound would be eliminated from your body. Good luck.
